/**
* @class Ext.BoxComponent
* @extends Ext.Component
* <p>Base class for any {@link Ext.Component Component} that is to be sized as a box, using width and height.</p>
* <p>BoxComponent provides automatic box model adjustments for sizing and positioning and will work correctly
* within the Component rendering model.</p>
* <p>A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing
* element, or one that is created to your specifications at render time. Usually, to participate in layouts,
* a Component will need to be a <b>Box</b>Component in order to have its width and height managed.</p>
* <p>To use a pre-existing element as a BoxComponent, configure it so that you preset the <b>el</b> property to the
* element to reference:<pre><code>
var pageHeader = new Ext.BoxComponent({
el: 'my-header-div'
});</code></pre>
* This may then be {@link Ext.Container#add added} to a {@link Ext.Container Container} as a child item.</p>
* <p>To create a BoxComponent based around a HTML element to be created at render time, use the
* {@link Ext.Component#autoEl autoEl} config option which takes the form of a
* {@link Ext.DomHelper DomHelper} specification:<pre><code>
var myImage = new Ext.BoxComponent({
autoEl: {
tag: 'img',
src: '/images/my-image.jpg'
}
});</code></pre></p>
* @constructor
* @param {Ext.Element/String/Object} config The configuration options.
* @xtype box

* or horizontally (by an HBoxLayout) according to the item's <b>relative</b> <code>flex</code> value

* <li>If there are two values, the top and bottom borders are set to the first value and the

* <li>If there are three values, the top is set to the first value, the left and right are set
* to the second, and the bottom is set to the third.</li>
* <li>If there are four values, they apply to the top, right, bottom, and left, respectively.</li>

* <p>If the <i>browser</i> is managing the height, be aware that resizes performed by the browser in response

* A Panel rendered into that target element must listen for browser window resize in order to relay its

title: 'Panel',
height: 400,
